Why in the world would you get in more debt with a new car when you have had such a difficult time already with the current debt you have now?
That is evident from your credit scores and your late pays. You can turn this around now before you make a fatal mistake of adding more debt.
Before considering a newer vehicle, get your current debt paid down so your scores increase. Pay off one of your cards entirely and the other one have less than 9% of the credit line used. See if you can GW the late pays off. This will get you into a much better buying position. It shouldn't take long. Others have done it here on this board.
How much is your current vehicle worth - not the trade in value but the KBB or NADA value? Rolling negative equity from this loan to the next loan is a bad, bad idea. Separate the sale of your current vehicle from the purchase of a new vehicle. It is a terrible idea to trade your vehicle -the car dealership makes out like a bandit. They low ball your trade AND they don't come down on the new purchase so you end up paying a very heavy price. To get a better price, sell your own vehicle rather than trade. You avoid that extra $4k right away. Once that $4k compounds over 6 or 7 yrs (you know the dealership F&I guy will stick you with that because you are an inexperienced car buyer) that $4k can balloon to $6k or more. Don't do it.
Once you get your current debt in line, go to a CU and find out what they will approve you for and get your loan there rather than at the dealership where they already have set you up for failure.
